FIBER-TREATING MACHINE.

Application filed November 26, 1927.

This invention relates to tiher treatingy machines.

(ine of the objects of thisinvention is the provision ot a tihcr treating machine and its associated system having; a safety explosion pipe thereon to permit of the release of ahnormal pressures to a point o1" safety.

A further ohjeet of this invention is the provision ot' an aeration tank and its associated elements which is adapted for cieaniin cotton linters. kapok. t'cti tihers and the iikc for the purpose ot removing dust and ,seeds therefrom.

A further ottici-,t1 o3' this4 invention provision of the combination with an ae tank and a closedcirculatory e ingr tihcrs of means for recei ving the accumulated dust in the aeration tank upon thc eren-- tion of a hack pressure in the system when tor instance the feed hopper is opened.

A further object ot' this invent ion is the pro-- vision of a system of the ahove type which permits of the automatic removal of dust from the aeration tank with each teedinjf operation.

This and many other ohieets are soufrht hy means of the invention.

This invention resides substantially in the construction, combination, arrangement and relative location of parts as will he more fully pointed out hereinafter.

Referringr to the drawings-- Figures t and 1^ taken together represent a side elevational view of the apparatus of this invention showin;Y the picker partly in cross section.

Figs. 2 and 2^ when taken together represent a top plan view of the system with some parts broken away.

Serial No. 235,767.

This invention in general relates to a system such as shown in the copending3 applicatif" et Kiliaen M. Van Rensselaer and myself .il No. 176,938, tiled March 2l, 1927.

l the treatment oi tihers in preparation for me in maitres-es, cushions.y and the like, it is nec ry' to hreak up the tihers from a matted. packed `form to a loose, fluffy condition and at the same time to remove therefrom att dust and foreign materials such as, 'ti-a instance. seeds in the case of those fibers which contain them. lt is usual to provide some torni ot' aeration tank connected to a clawed circulation .':Qvstem in which is connected a lilower for movingV the tihers through the 4 vstnt ln the use ot' such systems it has heen teun-'l that whcncwr the tiow of material is interrupted for any reason. such as when the inlet pipe to the blower is opened for the 'ein-t of fresh material. a hack pressure is created which forces the dust collected in the aeration tank from the tank at any available openings. This is. of course. undesirahle and this in venti-on has to do with an attachment for the aeration tank to receive this dust. In the arrangement of this invention the dust in the tank which has to he periodicallyY removed therefrom is automatically ejected from the tank to a receptacle at each feeding operation.

For a` hetter understanding of the invention reference is made to the drawings in which YI represents the floor or support for the apparatus and 2, a wall or partition. as for instance the wall ot a hnilding. The tank is shown eeneraly at 3 and is provided with a clean out door 4 for access to the interior. Near the hottom thereof is a screen 5 supported in an inclined position over a removahle drawer 6 so that the heavier particles of dirt and seeds from the tihers are permitted to tall therethrough into the drawer from which they may readily he removed from the tank. The top ofthe tank is provided with a screen Q which is enclosed hy a casing 7 to prnviflc :i separate chanilier at the top ot" the tank and in communication therewith.

An outlet pipeiis connected to the tank near the hottom thereof and is provided with ay hopper l] which has ay hinged cover lf2 through which fresh material may he ted into the system. The pipe 10 passes to and through the picker 13. The outlet of the picker 'is connected hy the pipe 't7 to the inlet of the hlnwer i8. A hjv-pass 1G connects pipe 2l conne'. is to the tanli S to dellert the, libcr v dor-:inwardly into the tank. valve l() is, provided at the iun''tion otf #s 2l and lt) whih isi o1, er al by nic-ane, ol' the lever 2i! and this Y'ool lever rh if: connected thereto bi' beans ot the wire 2l. fr

2. ln a fiber treating' machine, the combination with a tanh and a closed (circulatory fafsstein of a receptacle connected to Said tank to receive dust ejected therefrom whenever a back pressure is created in Said tank.

ln a liber treating machine, the combination with a tank, a closed conduit system lll() connected to said tank having a blower connected therein and a Vfeed hopper in said system ot a receptacle in communication With said tank to receive the dust in said tank whenever a baek pressure is Created by opening' said hopper.

4i. ln a liber treating machine, the combination with an aeration tank having a screen near the top thereof to form a separate chamber, an outlet conduit and an inlet conduit connected to said tank, said conduits being eonneeted to a blower, said inlet pipe being,T arranged to deliver tl e libers beineI treated to said tank below said screen of a pipe conneeted to said separate chamber and a receptacle attached to said pipe to reeeive dust trom said tank upon creation ot a back pres-` sure in said tank.

5. [n a tiber treatin;l machine, the combination with an aeration tank` a screen in said tank tor providing` a separate eon'ipartment near the top thereof, a n outlet pipe connected to the bottom of the tank having: a feed hopper therein, an inlet pipe connected to the top ot the tank and separated Vtrom said compartment by means et a detieetor plate, a. blower connected to said inlet. and outlet pipes, a pieker in one of said pipes. and an outlet connected to one 'ot said pipes and provided with a valve for isolatingl it therefrom, ot a pipe connect-ed to said eoinpartment at one end and to a dust receptacle at the other through a leaf valve so that upon the creation of a back pressure in said tank the dust therein will pass into said dust reeeptacle.

6. In a tiber treating machine, the combination with a te nk, a closed circulation system including` said tank ot' a dust receptacle connected to said tank through a conduit and a valve in said conduit adapted to operate upon the ereat ion ot a back pressure in said system to establish communication between said tank and receptacle.

7. In a fiber treating machine, the Combination with a tank. a closed circulation system inelutiinfr said tank of a dust receptacle eonneeted to lsaid tank through a conduit and. a one way leaf valve in said conduit adapted to operate upon the creation ot' a back pressure in said system to establish communication between said tank and receptacle.
